Blast in Baghdad’s Sadr City kills at least 16

At least 16 people were killed by a car bomb in a busy square in Baghdad's sprawling Sadr City district on Monday, while Islamic State attacks on military positions north of the capital killed 16 pro-government fighters dead, sources said.

There was no immediate claim of responsibility for the blast, which also wounded more than 40 people, but Islamic State regularly targets civilian areas in the heavily fortified capital, even after losing most of the northern and western territory it seized in 2014.

Three bombs killed 29 people across the capital on Saturday, and an attack near the southern city of Najaf on Sunday left seven policemen dead.

U.S.-backed Iraqi forces are currently fighting to push Islamic State, the Sunni Muslim militant group, from the northern city of Mosul, the fighters' last major stronghold in the country, but are facing fierce resistance.

The recapture of Mosul would probably spell the end for Islamic State's self-styled caliphate, but the militants would still be capable of fighting a guerrilla-style insurgency in Iraq, and plotting or inspiring attacks on the West.
